A student heats a beaker of ice and water and plots the temperature of the beaker as a function of time as shown below. Which statement among the following draws incorrect information about the plot?

 

Curve ‘bc’ represents increasing temperature and not the decreasing temperature of water upon further heating. 

From the plot, we can see that, curve ‘ab’ is a straight line without any fluctuations in y-axis directions, hence curve ‘ab’ represents a constant temperature. 

Also, curve ‘ab’ is observed at lower temperatures. Thus, curve ‘ab’ represents that ice and water exist at equilibrium and temperature is constant. 

After 25 minutes we can see that the state transformation takes place between ice and water. Here, ice completely melts to water. Curve ‘bc’ increasing temperature of water upon further heating.
